Tube Caps, Flanged
Marketlab Flanged Tube Caps are flexible polyethylene plug caps engineered for reliable closure of test tubes and centrifuge tubes. They feature dual flexible flanges that press against tube walls to deliver a leak-resistant and evaporation-resistant seal, suitable for applications involving centrifugation, agitation, storage, refrigeration, and freezing. The flanged design allows easy one-hand application and removal, and the grooved top improves grip. Available in sizes like 13 mm (and other common tube diameters) and a range of colors for sample organization.
